Necrotizing fasciitis is rare, so rare in fact that it's not a "reportable" disease. So when a 24-year-old Georgia girl fell from a zip-line into water in early May and contracted the disease, the story went viral. Aimee Copeland, a graduate student at the University of West Georgia, was riding a homemade zip-line when it snapped and she fell onto a rocky area of the Little Tallapoosa River—the gash on her leg ended up needing a whopping 22 staples. Days later, Copeland was having her left leg, right foot, and both hands amputated due to the flesh-eating disease.
